` iMPaovEMENT iN PAPER-FILES.

Specification forming part of Letters Patent No. 40,511 S, dated November 3, 1863.

To all whom it may concern.-

Be it known that I, SAMUEL THOMPSON, of San Pedro, in the county of Los Angeles and State of California, have invented a new and Improved Paper-File 5 and I do hereby declare that the followin gis a full, clear, and exact descri ption of the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a side eleva tion of inyinvention, partly in section. Fig. 2 is a transverse vertical section of the saine.

Similar letters of reference in both views indicate corresponding parts.

This invention consists in the arrangement of two round, square, or polygonal rods, one being provided with springs thatpress against the surface ofthe other or against one or more papers placed between the tworods or rollers and firmly connected to two arms, each -provided with a series of holes to form the bearings for the second rod or roller in such a manner that by adj Listing the movable rod or roller in the corresponding sockets of the arms a larger or smaller quantity of papers can be secured between the two rods or rollers, and the papers thus secured can be read or handled with the greatest ease and convenience.

The invention consists, also, in the arrangement of a movable longitudinally-slidiiig spring-gudgeon in one end of the movable roller in such a manner that by subjecting said roller to a strain or pressure in a longitudinal direction said spring-gudgeon is caused to recede and the roller is allowed to be taken out of or put in the several sockets of the arms with ease and facility.

To enable those skilled in the art to make and use my invention, I will proceed to describe it.

A A' are two rods made of wood or metal, either alone or both combined. These rods may be round, as shown in the drawings, or they may be square or polygonal, or in any other desirable form or shape, but as a general thing round rods or rollers will be preferable oii account of cheapiiess and of convenience.

B B are two arms, which extend from the ends of the rod A, at right angles to the same, being rigidly connected to` said ends. Each of these arms is provided with a series of holes or sockets, a, the corresponding sockets in two the arms being equidistantfrom the center of the rod A, and these sockets form the bearings for the gudgeons b b' of the rod A'. This rod may be made to correspond in form to the rod A, or it may be made' in any desirable shape of wood or any other suitable material. Its gudgeons are made of metal, and the gudgeon b' on one end is rigidly connected to the roller, whereas the gudgeon b on the opposite end is so arranged that it can be forced in a direction corresponding with or parallel to the axis of the roller. A spring, c, acting on the inner end of said gudgeon, forces the same out and holds it in its working position. By exerting a strain or pressure on this gudgeon in a longitudinal direction, or in a direction parallel to or coinciding with the axis of the rod A', it recedes and the rod can now be introduced into the corresponding sockets of the arms B; and if it is desired to take out the movable arm a longitudinal strain exerted on the rod A' in the direction toward the springgudgeon will cause said gudgeon to recede, so that the gudgeon b' comes out of its socket and by bringing the rod in an inclined position the gudgeon b can also be taken out.

C C are two dat springs, which are secured to the surface of the rod A between the arms B. If the rod A' is placed into that pair of sockets nearest to the roller A, and there is no paper between the two rollers, the loose ends of the springs bear on the surface or circumference of the rod A', and if one or more papers are placed between the two rods they are retained by the action of the springs. By shifting the movable rod from one set of sockets to another the space between the two rods can be increased or decreased, and consequently adjusted to any desired quantity of papers to be received between them.

What I claim as new, and desire to secure by Letters Patent, is-

l. The arrangement ofthe rod A, with arms B, sockets a, and springs, in combination with the adjustable rod A', constructed and operating as and for the purpose shown and described.

2. The longitudinally-sliding spring-gudgeon b in the end ofthe adjustable rodA', to operate in combination with the arms B, projecting from the ends of the rod A, substantially as and for the purpose specified.

SAMUEL THOMPSON.
